Bismuth (Bi) seems to become a metal, but the quantity of electrons available for electrical conduction is comparable to that of semiconductors. Actually, bismuth is called a semimetal. Molecular solids are often crystals fashioned from molecules or polymers. They are often insulating, semiconducting, or metallic, based on the variety of molecules inside the crystal. New molecules are consistently currently being synthesized, and plenty of are created into crystals. The volume of unique crystals Crystal is big.
景观水晶，就是包裹体组成各种造型特异的水晶，有的似山水，有的似人物，有些像文字，有些像动物，植物，器物等等。
Most solid components found in nature exist in polycrystalline form as opposed to as an individual crystal.

Though lengthy-range buy exists within a single grain, in the boundary between grains, the buying changes path. An average bit of iron or copper (Cu) is polycrystalline.
Crystalline construction is characterised by a geometrical, repeating pattern of symmetric molecular structure. The arrangement of atoms forms these requested, repeating styles.

水晶常以晶簇、晶洞形式产出，其中水晶洞一般存在于由火山喷发而形成的巨厚熔岩流层的火成岩与玄武岩中。火山喷发时所含的气体或热水溶蚀等作用导致岩层中出现大量的孔隙，当富含硅质矿物的流体进入较薄的熔岩孔隙中，且温、压条件合适时将结晶沉淀出水晶等矿物。
广义的包裹体是指宝石内部含有的与主晶宝石化学成分、物理性质等不同的物质。
